B4A Library Samsung TV Wrapper-library (sending remote-control code to Samsung TVs)

Kevin · Dec 5, 2012

... added to my app and sent on to my tester.

I'll post back with results when I hear them.

Thanks!!!

Kevin · Dec 7, 2012

Just wanted to post another message to say that the library works great and much thanks to moster67 for writing it!

I need to learn how to do this stuff! :sign0188:

in my Samsung TV 46C8000 dont go the example proyect moster67, there is some code of you example that i do not understand, for example, you wrote this

B4X:

'Activity module

   'These global variables will be declared once when the application starts.
   'These variables can be accessed from all modules.

   'These global variables will be redeclared each time the activity is created.
   'These variables can only be accessed from this module.

   'Do not forget to load the layout file created with the visual designer. For example:
   Activity.LoadLayout("two")

why you read MAC of celular? MAC is not from TV?, and i think IP from TV too, is ok?

Thanks.

@psdos

You need to pass on :

1) a name (name of your app for example),
2) mac-address of your android-device (this is a uniqueID which the TV needs)
3) host-address = ip-address of your TV
4) port = should be 55000 *

* = in my sample I used 55000 as a string by mistake but it should be an Int as the signature says. It seems like it works nevertheless (maybe B4A takes care of the casting)

susu · Feb 16, 2013

Hi Moster, I tried your wrapper on Smart TV 2012 (E series) and it worked. But how can we send text to TV?

Kevin · Jun 12, 2013

2) The java-code seems to run on the main-thread and therefore it will not work with ICS (perhaps also Honeycomb). In order to resolve this you must not target said SDK(s) in the Manifest. Perhaps using Agraham's Threading-library you can find a work-around although I have not tried it.

I recently tried changing my "target" API level in order to fix a market problem where Google Play showed my app as being incompatible with larger tablets. This broke the Samsung library and it was only a slight memory of reading the above quote that helped me figure out why it broke before I pulled more of my hair out.

I just wound up re-targeting a lower API for now, but...

Does anyone know how the code could be modified to force it to run in its own thread? Does B4A offer an easy way to force a certain library to run in its own thread?

Erel · Jun 12, 2013

There is no automatic way to "run a library in its own thread". Libraries should take care of such tasks internally. Note that there is no reason that your app will not be compatible with tablets if you target a lower SDK.

Kevin · Jun 12, 2013

I should have been clearer... No, the target SDK should not directly affect tablet compatibility in the market listing, but not having "x-large" screens listed in the manifest will.

Unfortunately you cannot declare x-large screen compatibility without targeting a higher SDK version in the manifest.

Doing this fixed 2 of my 3 apps as showing incompatible on a 10" Asus Transformer. It probably would have fixed the other if I hadn't had to change it back for reasons cited above.

moster67 · Jun 12, 2013

I actually made an update to this library some time ago where I added the "sendtext" function but I never posted it.

I might post this library and at the same time have a look if I can resolve the issue although it might be out of my league (I never had time to get to grips with Java-syntax). If anyone else would like to have a look, please do so. The source is in the first post of this thread.

Kevin · Nov 5, 2013

I tried fixing this the "cheating" way (using StrictMode) but I don't know if it worked or not since I don't have a Samsung TV. I really need to move my app on to a higher API level to address some other issues but this one is holding me back. Attached is my update to the library and below is the new code after my changes. The only changes I made were in the "RemoteSession.java" file, then I rebuilt in Eclipse.

I also tried forcing a timeout of 5 seconds but it still seems to wait almost a whole minute. I don't know Java...

I tried the library but does not work. I own a smart TV Samsung UE32H5500 (H series). In the module "remote" I added both the IP that the Mac-address of the smartphone that the Smart TV.
The smartphone has Android 2.3.3
The only result is a series of log discouraging
Log ("Something went wrong! What? No idea.")

Can anyone give me some suggestions?

Were you prompted on the TV-screen to allow your app to be used with the TV?
Also, check if the original app (which the wrapper is based upon) works with your TV. You can find it here. If it works, then I think the wrapper should work as well unless H-series requires extra or modified code not included in the wrapper.

Thank you for your quick response.

I installed SamyGo Remote.
The TV is recognized (192.168.1.4) but pressing any button the message
""192.148.1.4:55000 - Connection refused."

The H series is produced in 2014 and is not listed among those compatible with SamyGo (only B or C and D).

My TV is usually connected to the internet via wifi. I have to set something in particular TV?

It seems like the H-series is different from previous versions. If you search for other remote control apps, they indicate they are working on a solution for H-series so apparently there is no solution yet. It seems like port 55000 is disabled. You could try with a port-scanner and see if it is open.

Some links:

http://wiki.samygo.tv/index.php5/Samsung_TV_network_remote_control_protocol

I am afraid your TV might be not supported since Samsung seems to have changed things starting from the H-series. Mi spiace
